Ups, I though if some dup is detected I would be warned before submitting. Will remove it. Thanks! Edit: Seems I can not remove it by myself :-(

No worries - the previous entry is not front page, and I missed it. Glad I caught it the second time around.

HSV color scheme looks beautiful, but since it doesn't seem to have perceptually uniform color change we won't see it used in papers much :(

I think the rule for audio papers is linear change in color according to energy?

So this rep may lead us to hallucinate our conclusions?

For a moment I thought they would hypothesize that the patterns might be an actual “rendering” of what the birds were looking at, especially when I saw the 7th image which looks remarkably similar to a rodent.

Apparently I'm pretty far off, but just this idea of animals communicating images with sound waves was something I'd otherwise never have.

This is amazing. The GitHub repo has more information too, about how the common explanation of how our ears work (isolating sounds in an FFT-like-process) may be incorrect:

> Contrary to what you might think, our ears don't seem to rely on an FFT-like process to extract isolated frequencies. Instead, our ears detect periodic parts in the signal, although in most cases those periodic parts closely match the FFT frequencies. There is a simple experiment that proves this point:

Interesting train of thought.

Perhaps it's good to know that the x axis (from left to right) is temporal. So for someone/something to translate this to an image with some special sense would also necessitate some memory part.

With a big fantasy you could continue your hypothesis by comparing it to describing an object you see with words by telling the height of the outline from left to right.
